The secret of success is focus of purpose.

No Such Thing as Bad Results

There is no subsitute for hard work.

I have better use for my brain than to poison it with alcohol. To put alcohol in the human brain is like putting sand in the bearings of an engine.

I am a vegetarian as well as a passionate anti-alcoholic, because I can thus make better use of my brain.

Opportunity is missed by most people because it is dressed in overalls and looks like work.
